rre-IRON BREAKER.

j fo @ZZ whom it may concern.'

Be it known that I, ARTHUR A. AMBLER, a citizen of the'United States, residing in New Brunswick, New Jersey, have invented certain new and useful Improvements in Pig-ron Breakers, of which the following is a specification. f

One object of this invention is to provide a substantial rugged and convenient machine for breaking pig iron into suchlengths as are required to permit of their being easily charged and melted in a furnace the invention more especially contemplating a power operated device whereby ordinary lengths of pig iron may be quickly broken in half with the expenditure of a minimum of power and without danger to the operator of the machine.

A further object of the invention is to provide a power operated pig iron breaker including a novel form of slidable head and operating lever and the invention` includes relatively simple means for removably connecting a breaking tool to said head.

These objects and other advantageous ends I attain as hereinafter set forth, reference being had to the accompanying drawing, in which-V Fig. 1 is a side elevation, partly in vertical section, illustrating a -machine constructed in accordance with my invent-ion, and,

Fig. 2 is a frontelevation ofthe machine shown in Fig. 1.

As shown in the drawing the machine has a main frame Which includes a relatively ,heavy frame body 1 preferably in the form of a casting, having its upper portion overhung to provide avertical guide-way for a slidable head 2.

Below this over-hung portion 3 of the frame are mounted two parallel hardened bars 4, preferably spaced at equal distances on opposite sides of the line of movement of the head and having the frame cut away between them as indicated at 5. Said bars are preferably rectangular in section and rest on suitable plane portions of the frame where they are clamped by retaining plates 6, held in position by horizontalbolts 7. Said bars project above the adjacent portions of the frame and serve as widely separated, supports for lengths of pig ironto be broken, of which one is indicated in dotted lines at an.l

The main name of the machine also istY sladest-wa paralisi beams or am@ com nected to the frame body 1 on opposite sides thereof. These beams are connected to the frame body and to each other at the front end by bolts 9. As clearly shown in the drawing the frame body 1 is formed with lugs or shoulders at the tops and bottoms of` the bars 8-8 to assist in holding them in position. The said bars at their opposite or rear ends are connected together by a supporting block or member 10 so as to constitute a floor engaging brace or foot for the frame.' Said block pivotally supports. a motor suoli as a steam or hydraulic cylinder 11, which is permitted to swing in a vertical plane between the rear ends of the' beams 8 on a horizontal pivot 12, and has operative within it a piston 13, which through a suitable rod 14, is connected to the outer end of the long arm of an operating lever 15.

ThisV lever, which is fulcrumed by a pin or pivot 16 to the upper part of the frame body 1, is preferably made of two similar bars rigidly connected and having the two ends constituting its short arm extended on opposite sides Vof a shoe or nut 17. This shoe has on its Iopposite sides abutments 18,

engaged by the branches of the short arm of the lever 15. When the shoe is in the form of a nut, as preferred, it is threaded on an adjusting screw 19, whose lower end rotatably engages the sliding head 2, to which it the thickness of the bifurcated end of the lever 15, which variations may be due to inaccuracies of initial construction or due to wear. The lower end of the head 2 hasa sharp edged breaking tool 23, clamped to its fiatv lower face by a pair of cheek pieces 24, for which purpose the opposite sides of the said tool are inclined,`while thecheek pieces correspondingly formed to engagethe inclined surfaces'of said toolV to which they are held by a clam ing bolt l2x5, extending transversel] throu them and through the lower porE tion of tie head 2@ :tor a piece to be broken; a vertically reciprocable head operative in a line between the supports; a guide for the head; a breaking tool carried by the head; a lever pivoted to the frame for actuating the head to cause thetool to break a piece mounted on the supports; a power cylinder'tpivotally oonnected between the two parts of the beam at the rear ends thereof; and a piston in the cylinder operatively connected with the lever for actuating the head.

6. The combination in a breaking machine of a frame; two separated supports thereon for a body to be broken; a recip rocable head operative in ak line between said Supports; a nut adjustably connected to the head; a lever having a short arm engaging the nut; a motor for actuating the lever to operate the head; and a breaking tool for the head.

7. The combination in a breaking machine of a Jframe; tW-o separated supports thereon for a body to be broken; a reciprocable head guided on the frame to move in a line between said supports; a threaded member rotatively connected to the head; a nut adjustably mounted on said threaded member; a lever having a short arm operatively associated with said nut; and a motor for actuating the lever to move the head toward a body to be broken on said supports.

8. The combination in a breaking machine o a frame; two separated supports thereonvfor a body to be broken; a head slidably guided on the frame and having a breaking tool; a threaded member rotatively engaging the head and having a hand wheel thereon; a nut adjustably mounted on Said threaded member and having abutments; a lever fulcrumed on the frame and having a bifurcated arm engaging the abutments of the nut; with a motor operative on the long arm of the lever.

9. The combination in a breaking machine, of a frame, comprising a main cast body and a rearward extending beam; an operating shoe connected tothe head and having opposite abutments thereon; a lever ulcrumed on the frame and having a bie furcated arm engaging the abutments of the shoe; an adjustable nut threaded on the shoe and adapted to be engaged by the said bifurcated arm; and a motor for operating the lever. i

10. The combination in a breaking machine Vof a frame; two separated supports thereon for a body to be broken; a head slidably mounted in the frame and having a flat lower face; two cheek pieces mounted on opposite sides 'of the head and extending toward each other below the same; a breaking tool having inclined sides engaging the said cheek pieces and having a iat upper face held by .said pieces lagainst the fiat face of the head; and means for actuating the head to cause the tool to break a body on the supports.
